Leonardo DiCaprio and Cameron Diaz Friends With Benefits?

“Leonardo & Cameron FLIRT ALERT!” reads a headline from Star, which goes on to claim that Leonardo DiCaprio and Cameron Diaz are “quietly having a fun fling.”

The mag says DiCaprio “set off major sparks” with Diaz at the LACMA Art + Film Gala in L.A. on November 5, prompting witnesses at the museum event to suspect there was something romantic going on between them.

According to one so-called “source” at the party, “Every time Leo was pulled away to talk to someone else, he’d keep his eye on her.”

“Cam even blew him a kiss!” adds the “insider.”

How scandalous!

But don’t expect these two to come out as a couple anytime soon, warns Star, which explains the former Gangs of New York co-stars have a “no strings attached” type of arrangement.

A source close to the J. Edgar star assures Gossip Cop that DiCaprio and Diaz are just friends, noting, “Leo talks to a friend and Star writes something is going on… the magazine has actually fallen below the National Enquirer on the supermarket rack.”
